Fire safety? 

 First, building codes are safety codes, that is what they are there for and are not just local, they are every where. why wouldn't you want your buildings safe ?

Monthly Rent: $1,700PITI: $809Property Management: $221 (13%--I feel this is high & an opportunity to reduce this expense)Vacancy Rate: $119 (7%--this is based on our initial vacancy so I think it's high, but I'm using 7% to have a safety margin of error..

We leverage VA benefits and military housing to acquire properties and have a safety net in the process. 

One can weather a correction if they buy right and have that ever important 'margin of safety' in their cash flow numbers.  

I agree with the passive, but the fans are quite efficient, the estimated cost is about $50/year, to run. its also an easy sell to a tenant, because they think you are looking out for their best interest, since most landlords dont care, and few tenants even know what radon is, or that its a hazard. i see it as one more thing done for when im ready to get out, and sell, the fans last a long time, a friend has had his running for over 20 years now.  

In that case it might be considered a safety issue, especially if it weren't feasible to widen the halls and doors.  

This is a business, not a hobby.I have heard people accuse investors of always chasing the highest return to the exclusion of safety and prudence.  

Anyway, thanks for the article, It's a good reminder about fire safety.

Tons of life/safety issues & too many interior/exterior issues to list.
